Good grief, you look at the play again. If Nystrom lowers the shoulder he hits Letang dead red with the shoulder. His arm was tight to the body, sees he is going to lose the race and commits to check. Letang is leading with his head, is Nystrom not allowed to make contact with Letang because Letang has concussion problems and is irresponsible on the ice?
“Life is a storm, my young friend. You will bask in the sunlight one moment, be shattered on the rocks the next. What makes you a man is what you do when that storm comes. You must look into that storm and shout as you did in Rome. Do your worst, for I will do mine! Then the fates will know you as we know you.”
